The log also imdicates that it cannot create its own progress logfile (invalid argument)

As the others have suggested the user running the backup does not seem to have sufficient rights to do it and certainly does not have rights to the Program Files\Veritas directory.

Ensure that the user running the backup opens the BAR GUI using a right click "run as administrator" and is also a local administrator on that client to have enough rights to perform the backup and allow the backup to write to its own log file

Hope this helps

Don't forget to "Mark as Solution" if someones advice has solved your issue - and please bring back the Thumbs Up!!.

You are logging to the machine with chuik000 and this doesn't seems to have rights on directories and to BAR. Can you please try login using the local admin account and run the backup.

Also it's windows 7 so have you checked the firewall? or any security that might be stopping the manual backup process. Is there any antivirus running on the machine, try to stop it and try the backup again.If you try the automatic backup directly from Master or Media does it will work. Please try that so we can isloate the problem which seems to be your account or some right issues on win7 box.
